According to affidavits submitted to the U.S. Anti-Doping Agency, Crow was "in the room" in 2004 when Armstrong tried to persuade former teammate Frankie Andreu to "convince his wife Betsy to sign a statement retracting her claim" that Armstrong had admitted doping to his doctors.

It's unclear exactly how much Crow actually heard about her ex-boyfriend's performance-enhancing drug use. "I felt uncomfortable talking about this in front of her so I did not say much," Andreu said in the affidavit, the Huffington Post reports. Andreu's wife, Betsy, added, "Frankie did not want to discuss this in front of her."

Crow and Armstrong began dating in 2003, were engaged in 2005, and split up in 2006. Crow told Entertainment Tonight's Nancy O'Dell that she saw "bits and pieces" of her ex-fiancé's recent interview with Oprah Winfrey.

"I think that honesty is always the best bet and that the truth will set you free," she told O'Dell. "To carry around a weight like that would be devastating in the long run."

Back in September, right after Armstrong was stripped of his seven Tour de France titles, Crow opened up to Katie Couric about Armstrong's fall from grace.

"I felt bad for him, I felt bad for his family, and I kinda felt like the rest of America," she told Couric. "He is a hero that we watched and looked up to and admired."
